Referring to the drawings, the winding device 100 according to an embodiment of the present invention is made of a compact size is made of a wire or tape-shaped stretching member 30 in the case 20 having a narrow inner space of the winding The drum 40 is configured to be stored more wound.

Then, the stretchable member 30 can be quickly drawn out from the winding drum 40 for use, and after being used up, the winding drum 40 is reversely rotated by the elastic restoring force of the spring 50 that has been scaled up when taken out. Configured to rewind).

As a basic configuration of the present invention for this purpose, the winding device 100 of the present invention is provided with the case 20 and the cover 21, one side of the case 20 is formed with a slot (20a), the inside In the spring 50 and the winding drum 40, the drive rotation means 60 and the driven winding means 70 formed in a separate form are mounted horizontally arranged.

In addition, the driven winding means 70 includes a braking device 80 for controlling the rotation of the winding drum 40.

According to the exemplary embodiment of the present invention having such a basic configuration, the case 20 is formed in a disk shape in a long shape in a horizontal direction, and an upper side thereof is formed in an open shape so as to communicate with an internal space, and the cover 21 ) Is assembled to the upper portion of the case 20 is sealed.

On one side of the inner space of the case 20, two central axes are formed at appropriate intervals, one of which is a driving center axis 61, and the other of which is a driven center axis 71.

The drive rotation means 60 is made of a disk-shaped drive gear 63 formed on the outer periphery of the gear portion 62.

The spring 50 is accommodated in the upper inner side of the drive gear 63, and a shaft hole 64 is formed in the center thereof to be assembled to the driving center shaft 61. The boss 65 is formed to protrude so as to maintain a distance from the floor.

The driven winding means 70 may be configured to be separated from the driven central shaft 71, but is integrally formed in this embodiment.

Upper and lower ends of the driven central shaft 71 are fitted into the shaft support holes 22 formed in the bottom of the case 20 and the surface of the cover 21, and are engaged with the drive gear 63 and rotated thereon. A driven gear 72 is provided.

The winding drum 40 is integrally formed at the lower portion of the driven gear 72, and the upper surface of the winding drum 40 is slightly drawn in, and a plurality of locking protrusions are formed around the driven gear 72 on the surface thereof. The 41 is arranged in a radial form.

The locking projection 41 is formed with a vertical surface (41a) in the winding direction of the elastic member 30, the opposite side is formed of an inclined surface (41b).

Therefore, when the elastic member 30 is pulled, the locking hole 26 of the braking device 80 to be described later and the locking release operation are repeated to interrupt the rotation of the winding drum 40.

The outer periphery of the upper and lower ends of the winding drum 40 is formed to protrude in the form of a flange and is configured so that the elastic member 30 wound on the outer surface of the winding drum 40 is well wound without being separated outward.

In this configuration, the drive rotation means 60 and the driven winding means 70 are arranged so that the drive gear 63 and the driven gear 72 are arranged side by side to be engaged with each other. It can be seen that the winding drum 40 is disposed below the gear 72 so that the winding drum 40 is positioned below the driving gear 63 so as to overlap.

According to this configuration, the drive center shaft 61 and the driven center shaft 71 are formed at intervals so that the drive gear 63 and the driven gear 72 are engaged with the two shafts so that the drive center shaft 61 and the driven center shaft 71 are disposed therebetween. Sufficient space is formed to wind the elastic member 30.

Therefore, the length of the stretchable member 30 wound around the outer periphery of the winding drum 40 is increased, so even if the wound volume is increased, sufficient space is secured in the winding drum 40 so that the stretchable member 30 is limited in length. I can wind it up and keep it.

Here, the rotational ratio of the drive gear 63 and the driven gear 72 is the driven gear 72 to the drive gear 63 on the basis of the one rotation of the drive gear 63 according to the set ratio. The rotation speed may increase or decrease depending on the gear ratio.

For example, if the gear ratio of the drive gear 63 and the driven gear 72 is set to 1: 1, the rotation speed of the drive gear 63 and the rotation speed of the driven gear 72 are the same, so that the spring ( The winding drum 40 rotates at the same rotational speed in proportion to the winding speed of 50).

If the gear ratio of the drive gear 63 and the driven gear 72 is set to 1: 2, the driven gear 72 rotates two times when the drive gear 63 rotates by one, so that the winding drum 40 accordingly. The stretchable member 30 can be wound more.

When the gear ratio of the drive gear 63 and the driven gear 72 is set to be 1: 3 or more, the elastic member 30 is wound on the winding drum 40 within the rotational speed at which the elastic force of the spring 50 is not lowered. You will be able to wind more.

On the other hand, the braking device 80 is to control the rotational force of the winding drum 40, according to another feature of the present invention is configured to be slidably operated on the cover 21.

That is, as shown in FIGS. 3 and 4, the cover 21 corresponding to the engaging protrusion 41 formed on the winding drum 40 is inserted into the cover 21 in the form of a long hole so that the slide groove 23 is formed at the center of the bottom thereof. The formed knob seat 24 is formed, and the knob 25 is assembled to the knob seat 24.

The knob 25 is formed in a flat shape, the length of which is smaller than that of the knob seat 24, so that the knob 25 can be slidably moved, and the lower portion of the knob 25 extends downward through the slide groove 23 so as to extend the locking protrusion. It is the structure by which the latching opening 26 protruded so that it may be caught by 41.

The locking hole 26 has a pin hole 27 formed in the lateral direction so that the guide pin 28 is fitted into the pin hole 27, and the coil spring 29 is inserted into the outside of the pin hole 27. The locking hole 26 of the 25 moves horizontally to release the locking state from the locking protrusion 41 of the winding drum 40 and then returns to the original position.

An end of the guide pin 28 is supported by a guide protrusion 31 protruding from the bottom surface of the cover 21.

Referring to Figures 3 and 4 the operating state according to an embodiment of the present invention configured as described above are as follows.

From the assembled winding device 100, the user grabs the end of the elastic member 30 protruding from the slot 20a of the case 20 by the hand while holding the case 20 with the other hand. The winding drum 40 is rotated, and the driven gear 72 is drawn out through the slot 20a while being rotated in a direction opposite to the winding direction of the elastic member 30.

At this time, the catching protrusion 41 of the winding drum 40 is caught in the catching hole 26 of the knob 25, but the force of the coil spring 29 is applied by the force pulling the stretchable member 30. While winning, the locking hole 26 of the knob 25 is moved sideways along the inclined surface of the locking protrusion 41.

The locking hole 26 is moved while being guided to the guide pin 28 to release the locking state with the locking protrusion 41 and the winding drum 40 is rotated.

Here, when the catching hole 26 of the knob 25 passes through the catching protrusion 41, the catching hole 25 is applied to the repulsive force of the coil spring 29 fitted to the guide pin 28. It will be returned to its original position.

Therefore, even if the user does not pull the stretchable member 30 and the winding drum 40 is rotated in the winding direction, the vertical surface 41a of the locking protrusion 41 is not caught and rotated by the locking hole 26. .

The operation as described above is the state that the winding drum 40 is rotated while pulling out the stretchable member 30, the latch 26 is repeated by the inclined surface (41b) of the locking projection (41) The elastic member 30 is drawn out while the locking release operation is performed.

At the same time, as the drive gear 63 is rotated together by the rotation of the driven gear 72, the spring 50 is rotated together.

Since the inner end portion of the mainspring 50 is fixed to the driving center axis 61, the outer force is retracted inward, and elastic force is gradually accumulated in the mainspring 50.

Here, looking at the length of the extension member 30 is drawn out when the gear ratio of the drive gear 63 and the driven gear 72 is set to 1: 3 by the gear ratio as described above the drive gear 63 is Since the driven gear 72 and the guiding drum 40 are rotated three times during one rotation, the elastic member 30 can be drawn out a lot, and this action is sufficiently wound on the winding drum 40. It can be used by winding the elastic member 30 of many lengths in space.

In addition, when the elastic member 30 is rewound, when the knob 25 is pulled to one side, the locking hole 26 and the locking protrusion 41 are released, so that the elastic restoring force accumulated on the spring 50 is increased. The driving gear 63 is rotated together by the action that the mainspring 50 is reversely rotated.

As the driven gear 72 and the winding drum 40 are rotated in the winding direction by the rotation of the drive gear 63, the expansion and contraction member 30 is wound around the winding drum 40.

In this case, when the extension member 30 is drawn out, if the drive gear 63 rotates by one gear ratio of the drive gear 63 and the driven gear 72, the driven gear 72 rotates three times. The stretching member 30 can be quickly wound on the winding drum (40).

As described above, according to the winding device 100 according to an embodiment of the present invention, the stretchable member 30 wound around the winding drum 40 can be wound and stored while maintaining the appearance of the slimmed case 20. When the retracting member 30 is drawn out and rewound again, the retracting member 30 that has been drawn out at a rapid rotational force of the winding drum 40 by the gear ratio of the drive gear 63 and the driven gear 72. ) Can be easily rewound.

In addition, the winding device according to the present embodiment is excellent in the storage and portability when not in use, since the configuration of the case having a slim design with a thin thickness, it will provide a very good effect on the handling of the elastic member. .

On the other hand, according to another embodiment of the present invention to configure the appearance of the winding device in the form of a sphere (sphere) to implement a variety of winding device in the form of a spherical shape while winding a lot of elastic members wound on the winding drum It is configured for storage and use.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 5 is an exploded perspective view showing a winding device according to another embodiment of the present invention, Figure 6 is a longitudinal sectional view showing an assembled state of the winding device according to another embodiment of the present invention, Figure 7 is another embodiment of the present invention A cross-sectional view showing the operating state of the winding apparatus according to.

Referring to the drawings, the winding apparatus 200 according to another embodiment of the present invention is configured such that its appearance forms a sphere.

To this end, the case 120 includes a top case 121 and a bottom case 122 each having a hemispherical shape in order to construct a spherical shape by stacking components mounted therein in a plurality of layers. The drive rotation means 160 and the driven winding means 170 is arranged to be stacked up and down inside.

First, the driving center shaft 161 protrudes from the inner center of the upper case 121 as the driving rotation means 160, and the driven center shaft 171 protrudes from the lower case 122. .

In addition, the slot 122a is formed at one side of the lower case 122 in the drawing direction of the elastic member 130.

The spring 150 and the driving gear 163 are sequentially assembled to the upper case 121. The driving gear 163 in this embodiment is different from the driving gear 63 of the above-described embodiment. It consists of.

The drive gear 163 is configured to secure a space for accommodating the mainspring 150 above the hemispherical shape in which a portion of the upper surface is cut in order to be accommodated in the hemispherical upper case 121.

And, the upper side of the mainspring 150 is installed, the inner end of the mainspring 150 is fixed to the driving center shaft 161, the other end of the fixing projection protruding on one side of the upper surface of the drive gear (163). 164 is fixedly installed.

A bottom surface of the drive gear 163 is formed to be drawn in the upper side and the internal gear portion 165 is formed on the inner circumference.

In addition, the driven gear 172 and the winding drum 140 are integrally formed in the lower case 122 as the driven winding means 170.

One side of the driven gear 172 is configured to be rotatably installed an intermediate gear 173 for connecting with the internal gear portion 165 of the drive gear 163.

The intermediate gear 173 does not affect the gear ratio of the internal gear portion 165 of the drive gear 163 and the driven gear 172, and revolves around the driven gear 172 while simultaneously driving the drive gear 172. The rotational force is transmitted to the driven gear 172 while rotating by the rotational force of the gear 163.

In addition, the outer periphery of the upper and lower ends of the winding drum 140 is formed to protrude in the form of a flange is configured so that the elastic member 130 is wound on the outer surface of the winding drum 140 without being separated out.

Looking at the arrangement state of the drive rotation means 160 and the driven winding means 170 in such a configuration, the spring 50, the drive gear 163 and the driven gear 172 is the upper case 121 It is arranged to be stacked up and down in the inside, and is assembled so that the intermediate gear 173 is engaged to be connected therebetween, and the winding drum 140 is disposed in the lower case 122 below the driven gear 172. You can see that it is configured.

According to this configuration, the winding drum 140 is positioned inside the lower case 122, thereby ensuring a sufficient space for winding the stretchable member 130.

Therefore, even though the winding length of the elastic member 130 wound around the outer circumference of the winding drum 140 is large, the length of the elastic member 130 is limited to the winding drum 140 even if the wound volume is increased. I can wind it up and keep it.

In addition, as in the above-described embodiment, the rotation gear ratio of the driving gear 163 and the driven gear 172 is driven based on the setting ratio of the driving gear. The rotation speed may be increased or decreased depending on the gear ratio. This principle is the same as in the above-described embodiment, and thus description thereof will be omitted.

On the other hand, on the bottom of the winding drum 140, a plurality of engaging grooves 141 for intermittent rotation, as in the braking device 80 of the embodiment is formed in a radial arrangement.

To this end, the braking device 180 according to another feature of the present invention is formed through the bottom of the lower case 122 at a position corresponding to the engaging groove 141 is penetrated with a spring bombardment jaw 123 therein A hole 124 is formed, and the locking member 190 is assembled to the through hole 124.

The locking member 190 has a locking protrusion 119 fitted to the locking groove 141 at an upper end thereof, and the coil spring 124 is inserted into the locking protrusion 191 to the outside of the spring support jaw 123. It is elastically assembled in the middle portion thereof is formed to be thin and the step 192, the step 192 is configured to be supported on the outer surface of the through hole 124.

The lower end of the locking member 124 is formed to be thick and long, the end portion is formed with a hook portion 193 formed with a sharp end.

In the braking device 200 having the above configuration, the catching protrusion 125 is supported by the catching groove 141 of the winding drum 140, and when the catching portion 128 is pulled out of the coil spring 126. While the force is released from the locking groove 141 is to interrupt the rotation of the winding drum 140.

In addition, the hook portion 193 of the catching member 190 may be used by drawing out the stretchable member 130 in a state where the winding device 200 is inserted into the ground as needed.

In addition, according to another feature of the present invention, the middle portion of the locking member 190 is made of a flexible material so that the hook portion 193 can be bent.

Therefore, when the hook portion 193 of the catching member 190 is not used, when it is folded and inserted into the receiving portion 195 formed on the bottom surface of the lower case 122, the hook outside when the winding device 200 is carried. Since the portion 193 does not protrude, it is easy to carry and store.

In the present embodiment, the locking member 190 has been described as being integrally formed with the locking protrusion 191 and the hook portion 193. However, the locking member 190 may be separated and configured as another embodiment. Although not folded, the folding structure of the hook portion 193 may be configured to be hinged to the lower case 122 so as to be stored in a folding manner toward the accommodating portion 195.

When pulled up, the winding drum 140 is rotated, and the driven gear 172 is rotated in the opposite direction to the winding direction of the elastic member 130 while being pulled out through the slot.

At this time, the locking protrusion 191 of the locking member 190 is held in the locking groove of the winding drum 141, but the force of the coil spring 124 by the pulling force of the elastic member 30. The winding drum 140 is rotated while the locking protrusion 191 rides over the locking groove 141 while winning.

Here, when the locking protrusion 191 of the locking member 190 passes over one of the locking grooves 141, the locking protrusion 191 again becomes the next locking groove 141 by the repulsive force of the coil spring 194. Since the user does not pull the expansion and contraction member 30 so that the winding drum 140 may be reversely rotated in the winding direction, the locking protrusion 191 may not be caught and rotated by the locking groove 141. will be.

Since the above operation is a state in which the winding drum 140 is rotated while pulling out the stretchable member 130, the stretchable member 191 repeatedly releases the engaging groove 141 and the stretchable member. 130 is withdrawn.

At the same time, as the driven gear 172 is rotated, the winding drum 140 is also rotated together, so that the intermediate gear 173 is rotated together with the winding drum 140 to be surrounded by the driven gear 172. At the same time, the intermediate gear 173 is rotated in the opposite direction to the rotation direction of the driven gear 172.

Therefore, the intermediate gear 173 rotates the drive gear 163, where the intermediate gear 173 rotates in an inscribed state with the internal gear part 165. Is rotated in the same direction as the rotational direction of the intermediate gear 173, so that the drive gear 163 is rotated in the opposite direction to the driven gear 172.

As a result of this action, the driving gear 163 is rotated about the driving center shaft 161 so that the mainspring 150 is rotated together.

The mainspring 150 has its inner end fixed to the driving center shaft 161, and its outer end is fixed to the fixing protrusion 164. ) Elastic force is gradually accumulated.

Here, looking at the length of the extension member 130 is drawn out when the gear ratio of the drive gear 163 and the driven gear 172 is set to 1: 3 by the gear ratio as described above, for example, the drive gear 163 During the first rotation, the guiding drum 140 is rotated three times so that the stretchable member 130 can be drawn out and used a lot, and this action has many lengths in the winding space sufficiently secured in the winding drum 140. I will be able to use it by winding an elastic member.

On the other hand, when rewinding the elastic member 130, when the locking member 190 is pulled downward, since the locking protrusion 191 and the locking groove 141 is released, the elastic restoring force accumulated in the mainspring 150 As the mainspring 150 is reversely rotated, the driving gear 163 is rotated together.

When the intermediate gear 173 rotates in the opposite direction by the rotation of the drive gear 163, the elastic member 130 is rotated as the driven gear 172 and the winding drum 140 rotate in the winding direction. The winding drum 140 is to be wound around the outer circumference.

In this case, when the extension member 130 is drawn out, if the drive gear 163 is rotated one time by the gear ratio of the drive gear 163 and the driven gear 172, the driven gear 172 is rotated three times. The stretchable member 130 is quickly wound on the winding drum 140.

The hook portion 193 of the catching member 190 is folded and stored in the accommodating portion 195 when not in use, and the hook portion 193 when the hook portion 193 is extended and plugged into the ground when used. Since the winding device 200 is fixed to the ground by simply holding the stretchable member 130 and pulling it out easily.

In order to rewind the elastic member 130, the lifting member 200 may be simply caught by the lifting member 200 while the elastic member 130 is loosely held in the ground. Since the locking groove 141 is in the unlocked state, the elastic member 130 can be easily wound with one hand.

As described above, according to the winding device according to another embodiment of the present invention, while maintaining the outer shape of the spherical case, the elastic member wound on the winding drum can be more wound and stored, even when the elastic member is taken out and rewound. The stretchable member, which has been drawn out for a long time by the rapid rotational force of the winding drum by the gear ratio of the drive gear and the driven gear, is easily rewound.

In addition, the winding device according to the present embodiment is excellent in the storage and portability when not in use, since the configuration of the case having a compact design of the spherical size, the handle on the use of the elastic member provides a very good effect will be.

As described above, the embodiments of the present invention have been described and illustrated, but the present invention is not intended to be limited to the above embodiments, and various modifications may be made without departing from the scope of the present invention.

As described above, the present invention is configured to be able to store more stretched members inside the winding device case having a limited internal space, as well as to be able to quickly withdraw and rewind the stretched members from the winding drum. In order to implement a variety of product design in the form of a slim product design or sphere of the winding device to provide a beautiful appearance, as well as excellent storage and portability when not in use, Handleability will provide a very good effect.
